Assessment of Acoustic impact for the wind farm in Algeria

The aim of this article is to evaluate noise impact produced by wind farm, the ISO 9613-2 standard method it be used to evaluate the acoustic impact for one row of twelve wind turbines from South-South-East (SSE) to North-North-West (NNW), 208 m of distance between each two turbines. The results obtained show that the noise level of this wind farm is approximately 45 dB at 236m from the nearest wind turbine and it is corresponds to the noise inside quiet house, while the noise level produced is acceptable, except an ellipse (1.87km²) around of the wind turbines, which the noise is greater than 45dB; we can conclude that these noise levels are consistent with the national standard (Executive Decree No. 93-184 of July 27, 1993, regulating noise emission).
